GUI Question: why are certain features bound together independent of "group panel elements"?

Not saying this is the only problem ;), but one thing is that for waveform displays like this, if you change the size of the display, you sometimes need to update the number of objects... 1 object per pixel, or similar... It doesn't have to work that way, but does in this case.

Reaktor does a weird thing where it tries to adjust the view port within the window to make stuff visible... so if you have a visible macro, and then you drop another visible item into it with a smaller size, you can drag it around... if there are two or more items, and you drag one around, the macro window will resize to fit so that you can position items... if there are three you can set up situations where when you drag one item, the others move instead as the view port resizes (this happens when the item you are dragging is on the left (or top) of both the macro window and the Reaktor edit pane.

The thing with stacked macros is that the same rules apply except the viewport size of the stacked macro is partially fixed (has a minimum size which is set in parameters), so it behaves in strange ways. This can be tricky, because sometimes the only way to fix it its to cut some macro out and then paste it back in to reset the position offset... however, this can change the order within the stacking mechanism, so you need to cut and past each and every one in the correct order!. It's a faff, and over time you start to get better at getting it right first time, or just starting again :). You learn to spot when it's just got too far away from you to even consider trying to fix it.

This is a shame because stacked macros are a potentially powerful mechanism, and it's technically possible to build up complex stuff like nested drop down menus, but it's impractical because as soon as something goes wrong with the placement, it's very difficult to fix.

One useful tip is that you should avoid dragging manually, instead, select items in the edit pane, then select the GUI pane by clicking in it's status bar, then use cursor keys in combination with SHIFT+CTRL for fine adjustment... That way you can easily select what you want to move, then controllably move it a click at a time... much better.

Another tip is to zero out the 'borders' of macros and stacked macros. Borders can be useful sometimes to centre text etc., but should be used at the end if all else fails.

Yet another tip for stacked macros is that when editing, depending on the situation, you might need you manually set the panel index in the edit pane using a constant for editing purposes (or an external knob if you need to easily flip between layers), then when all the layers are set up correctly, reinstate the page indexing logic. Otherwise you will be on a fast track to Stacked Macro hell :). This is very useful for stuff like the name/value on Blocks knobs, because they flip based on a mouse over timer.
